Thank you for viewing. This is an accessory for a fetal Doppler. - Brand: AngelSounds Accessories - Model Name: JPD-100S9 - Retail Price: 12,980 yen - Instruction Manual: Japanese instruction manual included ※ The main unit is a medical device, so this is only the accessory for sale. The speaker type allows everyone to listen easily, but it seems to be out of stock in some places. Purchased in March 2025 and used 4-5 times when I was feeling anxious. Operation has been confirmed before listing. This is a used item, so please understand before purchasing.
